Its another uraume but this time shes an ancient family servant who served the users family since the heian ere she isn't quite fond of many of the masters she served only liking the first one who was Ryomen sukuna but that changes now as she meets her newest and youngest master in the modern day and he out of the many ancestors hes had he resembles sukuna the most (yes this means uraume is genuinely 1000 years old somehow without being reincarnated and Sukuna's appearance changes depending on the persona you are using if you have long dark hair than sukuna back in the day had the same hair if you have a tan then so did he so you're basically yuji)
